One is predisposed to like State Senator Lee Zeldin, an affable Army veteran who is seeking for the second time to take Representative Tim Bishop’s seat in Congress. However, even though he ran for the First District post in 2008, won a seat in the New York Legislature in 2010, and then beat back a Republican primary challenge this year, Mr. Zeldin has very little to say for himself, which is perplexing. Instead of presenting his own ideas he repeats party positions on school vouchers, weak gun laws, and the eventual privatization of Social Security.
